I was changing the countershaft sprocket (the previous owner had installed a 16 tooth sprocket) on my 400ex yesterday and noticed my chain is shot. I'm gonna replace the rear sprocket also. What is the best value? I notice the Primary Drive pieces are a good deal less than Renthal, DID, RK, Sunstar etc. Are these any good? I want steel sprockets and an o-ring chain. I only do trail riding with my quad, so I don't need the latest, trickest pieces. What do you guys recommend?

 

Do not wast your money on Primary Drive they are cheap. I like JT sprockets and RK O-ring chains. I get around two years out of a set of them. You can get a set for around $80.00.

 

Anyone else have an opinion?
